VIOLA. 



V. rotundifolia is a stoutly running thing, quite prostrate in growth* 

 with rounded-heart-shaped leaves, minutely downy at flower-time, 

 and with wide vague scallopings at their edge. The flowers are bright 

 yellow violets, and their three lower petals are veined with brown. It 

 lives in the cold woods of North America. 



V. Ruppii. See V. canina stricta. 



V. Rydbergi is an especially brilliant form of V. canadensis, q.v. 



V. sabulosa=V. Gurtisii, q.v. 



V. sagittata is a stalwart North American Violet of 10 inches, with 

 lavender-lilac flowers and arrow-head foliage. 



V. sarmentosa is the same as V. sempervirens, an evergreen Cali- 

 fornian Violet with yellow flowers. 



V. scahriuscula comes quite close to V. pubescens and V. bijlora, 

 though it is usually larger and leafier and rather coarser than the 

 Two-flowered Violet. It shades into V. pubescens, but the leaves 

 are earlier, some one or three from the base, and then three or four 

 stems, shorter, leafier, and less downy than in V. pubescens. Like 

 the rest of the group, it haunts the cold, damp places of the moun- 

 tains. It is a much better garden-plant than V. bijlora. 



V. Schultzii is the very rare pale-yellow Alsatian form of V. 

 canina, q.v. 



V. sciaphila. See V. hirta. 



V. scopulorum is a condensed, diminished, and deeply coloured 

 variety of brilliant V. canadensis. 



V. Selkirkii makes clumps of handsomely scalloped leafage much 

 too large, as a rule, for the huddled little lilac violets ; it is a small 

 and rather delicate thing, running underground. 



V. septentrionalis has variable flowers. It lives in the moist open 

 woods of America, beneath the pines, for instance, and may be known 

 from V. Novae Angliae, among other things, by the invariably blunt 

 end to the heart-shaped foliage. It is remarkably pretty. 



V. silvestris is the woodland cousin of our Dog Violet, abundant in 

 every copse. 



V. sororia has the same ample clumped habit as V. papilionacea, 

 and occupies the moist places of Northern America even to the very 

 dooryards. It is a variable species ; the leaves are often largely 

 triangular from their heart-lobed ample base, but sometimes rounded 

 and running abruptly to a point. The stems of the many purple 

 violets are about the same height as the leaves. 



V. spathulata is a Caucasian tuffet of no especial merit. 



V. speciosa copies in all things V. macedonica, but has larger 

 flowers.
